The OnStar FMV mirror gives you the benefit of their famous emergency response without buying a new car. It's like they're staring right back at you, keeping you safe. Creepy, sure, but effective.

The add-on device provides automatic crash response, turn-by-turn navigation, hands-free calling, and the amenities OnStar has been offering up to now including roadside assistance. Basically, if you crash your car after misunderstanding the directions and have no idea where you are, you've covered. It's available now for pre-order at Best Buy, and will retail for $300, with a $75 installation fee and $18.95 subscription. [OnStar, Engadget]
